I found a really awesome mommy cream on Amazon.com
I fear a lot of issues with stretch marks are genetic but staying hydrated, moisturizing your skin daily, and keeping a good diet will all help though... here's to hoping anyway!
Be careful with vitamin C too much can be harmful. Research will tell you that also
I've been using bio oil. Look it up on Amazon and read the reviews
Eat vitamin c I've read it helps your skin stretch.
Cocoa butter also helps but don't use a thick moisturizing cream use a thin one so it can actually get into your skin instead of sitting on top
Unfortunately stretch marks are hereditary so not much can be done to prevent them. I use coconut oil, a Shea butter and Curel depending what I have on hand. Most important, I think, is to keep your skin hydrated.
